Why Aisle?

Aisle is redefining how enterprises secure their software with an AI agent for autonomous vulnerability remediation. Vulnerabilities are the #1 root cause of cyber incidents, yet most organizations take weeks or months to patch what attackers exploit in days. We’re changing that.

Our mission is to protect democratic societies from the most sophisticated cyberattacks. We do that by giving organizations - including those operating critical infrastructure - the power to harden their systems and resolve security issues at superhuman speed and scale. Backed by world-class founders and advisors, we’re creating a new category in cybersecurity at the intersection of AI, automation, and enterprise resilience.

We’re a small, talent-dense team spread across the US, Europe, and Israel. We value high ownership, high velocity, and low-ego collaboration. If you want to work with world-class minds in AI and security, thrive in fast-moving environments, and care about solving one of the toughest challenges in tech, Aisle is the place for you.

What we’re looking for

  • 5+ years of experience in offensive security, penetration testing, or red teaming, ideally within high-growth B2B SaaS or cloud-native ecosystems.

  • Deep technical proficiency in identifying vulnerabilities across web applications, APIs, and cloud infrastructure (AWS, GCP, or Azure).

  • Mastery of the attacker mindset; you should be an expert with industry-standard tools (Burp Suite, Metasploit, Kali Linux, etc.) but also capable of writing custom scripts to automate exploits.

  • Strong understanding of modern architecture, including containerization (Kubernetes/Docker), CI/CD pipelines, and OAuth/SAML identity flows.

  • Excellent communication skills, specifically the ability to translate complex technical exploits into actionable risk assessments for non-security stakeholders.

  • Bonus points for recognized certifications (OSCP, OSCE, GPEN), a history of responsible bug bounty disclosures, or active participation in the CTF community.

What you’ll do

  • Execute continuous security assessments and deep-dive penetration tests across our entire product suite and internal infrastructure.

  • Proactively hunt for threats and architectural weaknesses that automated scanners might miss, ensuring our defenses stay ahead of evolving attack vectors.

  • Collaborate with engineering teams to provide "remediation-ready" guidance, helping them squash bugs and implement secure coding patterns.

  • Design and run Red Team exercises to test our detection and response capabilities, providing a feedback loop for our Blue Team operations.

  • Advocate for a "security-first" culture by conducting internal workshops and helping developers understand how to think like an attacker.

  • Help build the foundation of our offensive security program, influencing the tools, methodologies, and long-term security roadmap at Aisle.
